The status display indicates “FBC”
when the FBC function is on.

*1 Not displayed when the menu option OTHER
DISPLAY in the DISPLAY SETUP screen is set
to OFF.
The following phenomena that may occur
in video that includes flash light is due to
FBC compensation and not indicative of a
malfunction.
• Moving subjects may appear to be
stationary for an instant.
• Resolution decreases in video exposed to
flash light.
• Horizontal lines appear in video footage
exposed to flash light.
Using FBC
FBC goes on when the brightness of the
lower half of the image differs markedly from
the previous half, which could be caused by
light from a camera flash or other strong light
source. Since FBC may be incorrectly activated
in certain shooting environments, for example,
in zooming that includes a bright window,
be sure to use the function only for shooting
footage exposed to flash light.
In some shooting environments adequate FBC
effect may not be obtained even when a flash
goes off.
FBC requirements
• You can use FBC in the “FBC operation
enabled mode” below.
• Even if the FBC function is switched ON, it
will be forced to OFF if the mode is switched
to one not shown in “FBC operation enabled

When you wish to use this mode again, set
the camera to a mode shown below then
press the USER button and switch the FBC
function ON.
• Even if the FBC function is switched ON, it
will temporarily be switched OFF if shutter is
switched ON or the digital zoom is operated.
The FBC function returns to the ON state after
shutter or digital zoom is switched OFF.
• The FBC function is switched OFF if the
power switch is set to OFF.
